OWEN r. LAPHAM, OF CLEVELAND, OHIO.

WRINGER.

SPECIFICATION forming part of Letters Patent No. 245,638, dated August16, 1881.

Application filed March 25, 1881. (ModeL) To all whom it may concern Beit known that I, OWEN T. LAPHAIVI, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and useful 5Improvements in Wringers; and I do hereby 1 had to the accompanyingdrawings, which form part of this specification.

My invention relates to clothes wringers; and it consists in certainfeatures of construction and combinations of parts, as will hererinafter be explained, and pointed out in the claims.

In the drawings, Figure l is an isometric view of my wringer. Fig. 2 isa vertical sec tion of the same.

13 B are the rolls.

0 is a shaft, which is made preferably of wood. This shaft is providedwith three cams, one at each end, 0 c, for operating the tension of therolls B B, and one in the center, a, op-

The center cam, a, is provided with a handle or lever, D, for operatingthe shaft 0 and its cams. This handle, in turn, is provided with aprojection or lug, d.

E is the clamping-frame, which is provided at its upper end with a crosspiece, F. This clamping-frame E is fastened tothe frame A by means of abolt, H, which passes through said frame A, and also through theclamping- This bolt H is provided with a thumb-nut, I, which acts as anadjustable fulcrum for the clam ping-frame E.

e is a spring, which may be of wood or metal, the ends of said springengaging with the cams c c, and the center resting on the cross-bar t,

the ends of said cross bar '5, in turn, resting upon and operating thejournals of the upper roll.

The operation of the clamping device is as 4 5 follows: When it isdesired to use the wringer the legs of the frame A are placed inside ofthe tub, and the legs of the clamping-frame E are placed ouside theshaft- O, and its eamscc and a are revolved in the direction of thearrow in Fig, 2 by means of the lever or handle the side of the tubbetween them and the legs of the frame A. At the same time that the camit operates the clamping-frame E the cams c 0, coming in contact withthe ends of the spring 6, operate, through said spring 6, the bar 1',and the journals of the roll, to force the top roll against the lowerone. When it is desired to unclamp the wringer from the tub it isobvious that the act of unclamping will relieve the rolls from anytension. The lug or projection d on the handle D, coming in contact withthe outside of the bar F, operates to draw the top of the clampingframeE in, and hence force the legs out and relieve the tub from their grasp.

I may provide the top of the legs of the clamping-frame with a spring,either of metal or rubber, which acts to keep the wringer in place onthe tub before it is clamped by means of the cam a, without thenecessity of the operator holding it there.

It will be seen that the cam a, after it has operated to clamp themachine to the tub, will not act to further force the upper part of theclamping-frame E out; but the cams c c, as they are revolved further,will act to increase the tension of the rolls.

I may also provide the lower part of the legs of the clampingframe withsprings l, which will act to force the said lower part of the legs outwhen the cam a releases the cross-bar, and bring said cross-bar inposition to be operated upon by the lug d.

What I claim is-- 1. In a clot-hes wringer, the combination,

with the wringer-rolls and clamping-frame, of

a rock-shaft journaled in the frame of the wringer, said rock-shaftprovided with a cam that engages with the clamping-frame, and cams whichengage with the tension-springs of the wringer-roils, substantially asset forth.

2. In a clothes-wringer, the combination, with the clamping-frameprovided with crossbar F and spring l, of the rock-shaft O, providedwith handle D and lug 61, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence oftwo subscribing witnesses.

OWEN T. LAPHAM.
